BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a longitudinal sectional view of a blender including a base for a blender according to an embodiment of the present invention, Fig. 2 is a longitudinal sectional view of the blender of Fig. 1 with the bottom wall separated, And Figure 4 is a longitudinal section view of a blender comprising a base for a blender according to another embodiment of the present invention.

A base 50 for a blender 100 according to an embodiment of the present invention includes a housing 51 for accommodating a fan 62 that is coupled to a driving device 60 and a driving device 60 to be rotated, 51, and includes a sound-absorbing chamber for absorbing noise transmitted by the cooling air generated by the rotation of the fan 62. The sound-

On the upper side of the base 50 is mounted a container 90 containing, for example, food to be crushed or blended. A processing member for processing food, for example, a cutting edge 91, is provided inside the container 90. When the container 90 is mounted on the upper side of the base 50, the driving force of the driving device 60 mounted inside the base 50 can be transmitted to the cutting edge 91, for example, mechanically.

An operation panel 53 for controlling the operation of the blender 100 may be provided on the front wall 52 of the housing 51. The rear wall 54 of the housing 51 may be provided with a suction port 55 for allowing air to flow into the outer rotor of the base 50 when the fan 62 is operated.

The driving device 60 accommodated in the housing 51 is mounted inside the housing 51 with the rotation axis of the rotor 61 being vertical. The upper end of the rotary shaft of the rotor 61 is used to transmit the driving force to the rotary blade 91 and the lower end of the rotary shaft is used to transmit the driving force to the fan 62. [

The interior space of the housing 51 in which the drive device 60 is disposed is communicated with the suction port 55 and communicated with the fan hole 82 of the sound-absorbing chamber upper wall 80 as described later. When the driving device 60 is rotated, the fan 62 is also rotated so that air is introduced into the interior space of the housing 51 through the inlet port 55 and flows into the sound absorbing chamber described later through the fan hole 82 .

The sound absorbing chamber is provided on the lower side of the drive device (60). The sound-absorbing chamber includes a sound-absorbing chamber upper wall 80 in which a fan hole 82 is formed, a bottom wall 57 constituting the bottom of the housing 51, A part of the side wall (not shown) of the housing 51 surrounding the space, and a lower part of the inner side wall 85.

The inner surface of the bottom wall 57 is provided with a floor absorbing material 70 capable of absorbing the noise of the cooling air flowing from the fan 62. The floor absorbing material 70 may be made of a material known in the art, and may be composed of, for example, a microporous sponge or a sponge having a honeycomb shape.

3, the bottom wall 57 is the largest in width and rectangular in shape and has an inlet portion 357 located immediately below the fan 62, a downstream portion extending downstream of the inlet portion 357, And a discharging portion 157 extending to the downstream of the converging portion 257 and having a constant width.

The bottom wall 57 can be separated from other portions of the housing 51, as shown in Fig. Therefore, when the sound absorbing effect of the sound absorbing material 70 provided on the inner side or the upper side surface of the bottom wall 57 is covered with foreign substances such as dust or the like and the sound absorbing effect is lowered, the bottom wall 57 is separated and the soiled sound absorbing material 70, (70).

Further, as shown in Fig. 4, the upper portion of the sound absorbing material 70 'may be formed in a concave-convex shape or a waveform. In this case, the area of contact between the sound absorbing material 70 'and the cooling air becomes wider and the flow of the cooling air becomes more turbulent, so that the sound absorbing material 70' can more effectively absorb the noise transmitted by the cooling air .

On the other hand, the sound absorbing materials 70 and 70 'attached to the bottom wall 57 and the sound absorbing material 170 provided on the inner or lower surface of the upper wall 80 of the sound absorbing room, And also serves to reduce the vibration propagated through the structure of the housing 51 and the base 50. [0051] As shown in FIG. Therefore, the blender 100 having such a configuration can alleviate the vibration as well as the noise generated during the operation, thereby increasing the satisfaction of the user.

The fan hole 82 may have a fan hole outlet 81 whose diameter increases toward the lower side as shown in the figure. The position of the fan hole 82 is arranged on the upper side of the inflow portion 357 of the bottom wall 57 when viewed in a plan view. Accordingly, the cooling air discharged from the fan 62 can collide with the sound absorbing members 70 and 70 'in a substantially vertical direction, whereby the cooling air can penetrate deeper into the sound absorbing members 70 and 70, The removal effect can be improved.

The converging chamber 72 downstream of the inlet chamber 71 includes a converging portion 257 of the bottom wall 57, a pair of second inclined walls 84, and a sound absorbing chamber top wall (corresponding to the converging portion 257) 80). The cross-sectional area of the converging chamber 72 becomes smaller toward the downstream side.

The discharge chamber 73 downstream of the converging chamber 72 is connected to the discharge room 151 of the bottom wall 57, the pair of side walls (not shown) and the sound absorbing chamber top wall 80 corresponding to the discharge portion 151, In particular, the portion including the first inclined wall 83. In this case, The discharge chamber 73 increases in cross-sectional area toward the downstream, and then becomes constant. The discharge chamber 73 is connected to the discharge port 56.

A vibration proof rubber (58) may be provided on the bottom of the housing (51). The vibration proof rubber 58 serves to buffer the vibration of the blender 100 between the bottom surface on which the blender 100 is placed and the blender 100.

Hereinafter, the operation of the blender 100 including the base 50 according to the embodiment of the present invention having the above-described configuration will be described.

When the container 90 is placed on the upper side of the base 50 after the food is put in the container 90 and the rotor 61 of the driving device 60 is rotated using the operation panel 53, 62 are also rotated together.

At this time, air is introduced into the housing 51 through the suction port 55 by the rotating fan 62 to cool the driving device 60, and then flows into the inlet chamber 71 through the fan hole 82 . The cooling air flowing into the inlet chamber 71 contains and transmits the noise generated from the vibrations of the driving device 60, the fan 62 and the housing 51, but the sound absorbing materials 70 and 70 The noise level of the cooling air flowing out of the housing 51 through the discharge port 56 is low.

Further, a converging chamber 72 is disposed between the inlet chamber 71 and the outlet chamber 73, so that the pressure in the inlet chamber 71 can be maintained above a predetermined value. Further, it is not necessary to block or block the flow of cooling air.

It will be apparent to those skilled in the art that various modifications, adaptations, modifications, and substitutions can be easily made by those skilled in the art without departing from the scope of the invention as defined in the appended claims. Be careful.
